BT Smart Hub 2 Keeps disconnecting

[mrberta]

This seems to happen most evenings between 9pm to 11pm. BT came down and said there was no issue with the router and also installed a new line yet the issue still happens most days. (BT Smart Hub 2)

Its BT that is forcing the restart via TR069, which is used for remote management.

21:32:39, 04 Jan. System restart, reason: TR69

Not sure why its doing it every night.

Its one of the disadvantages of using an ISP provided router, as you have no control over it.

Thanks for the reply @Keith_Beddoe  But this happens most days, why would they be force rebooting me everyday? I can get logs from other days if that helps

[Keith_Beddoe]

No idea, I suspect perhaps there is an issue with the home hub, perhaps the configuration is corrupted?

You could try a factory reset of the home hub, to see if it helps.

[mrberta]

I have done a factory reset many times and I still have the issue most days. I'm not sure if all error logs are the same code so once it does it again I will post the new entries

[imjolly]

When you did the factory reset by pressing recessed button back did you hold button until the hub lights flashed ?  You would need to turn off smart setup after restart

looks like hub is trying to update firmware and failing

[mrberta]

@imjolly How do I turn off smart setup? Will turning that off stop the TR69 disconnects? Or will I have to get another router to avoid this issue?

Also had one of these in my logs recently not sure what it is I can't find anything online for it "DoS(UDP Loopback)"

[Keith_Beddoe · Accepted solution]

The only way to stop the TR069 disconnects, is to use a third party router, BT has no control over that.

@Keith_Beddoe Ok thank you! I love my BT router but TR069 disconnects happen at the most annoying times! I'll look into a new router! Thank you for the information.
